The present invention relates 'to safety windows and has special reference to a construction of the window and the gate thereon line 6:6 of Fig.1:

.mItf's of 'oursetobe invention is not. to be considered as limited.

fore. e

It is a custom to provide window gates which open and close with motion of the window. If the gate is provided with afastener by which it may be detached'from the movable sash, there is danger ofthe gate 110 being left detached and hence of the'window being left unprotected if open. If the'gate is more permanently attached, considerable difliculty or inconvenience may be experienced in washing the window or in removing the gate to wash the window.

The present invention provides a window gate of novel construction which may be permanently associated with awindow sash in.

which the window glass is mounted in a movable frame. 1

One object of the invention is to provide,

7 window sashes with a movablymounted glass therein, such as a door-like mounting. Another object of the invention is the pro- -vision of a novel gate that is compact in folded from and suitable for permanent association with the sash.

Still another object of the invention is the provision of a casing to house the folded gate. I

Various other objects and advantages of the invention will become apparent from the following description of the invention as it is illustrated by the several embodiments 35 shown in the accompanying drawings, in

which Fig. 1 shows a window open to expand a ate. 1 b Fig. 2 is a side view of the window of Fig. 1 on line -22 of Fig. 1.

. Fig. 3 is a view of the window with the gate closed. r

Fig. 4 is a side view of a regular length windowshowing the gate mounted in the out side runner, and protecting casing.

Fig. 6' is a cross-section of the slidingjoint to or bythe disclosuresshown in the drawmg, as will appear more fully hereinafter. The invention is susceptible to change and modification to include other embodiments whlch may falll'withi-n the spirit/and scope of theappended claims.

- In thedrawings a window casing 10 is illustrated in which upper sash 11 slides between runners 12 and 13 and lower sash 14; slides between runner 13 and 15.

Each sash carries a frame16 inwhich a glass'l7' is mounted. Theframe'is suitably removable from the sash being shown hinged.

thereto in door-likefashion by hinges 18 and 1 :19, so arr'angedthat the glazed frame swings into h 'D-0m 'A lock'or fastener 20 ,is in -di'cated forthe glass carrying frame.-

The lower sash is shown inlFigs.-1iand.2 to be shorter than is customary, to provide an extra space at the fbottom for mounting; a closedwindow gate. 1 'lThe-gateis one which -may. be, compactly'and tightly closed. 1 p --Acasing or angle plate 21 may beemployed j mounted within runner space sothat itsftop infront of the closed gate, and it is shown I 22' provides a stop for thelower sash 1 4.

- {The gatewhich is employed fcomprisesa plurality of parallel bars connected fbyexpansible mechanism, preferably of the tog s,

gle-like structure, which do not prevent close understoodthat the fitting of theb'arsin the folded'form of the gate 111 this present instance each bar 23 -is a slotted hollow bar which comprises'two channel strips 24 and 25 (Fig. 6) spaced apart with the channel o'peningsfacing each other. The channels are rigidly secured in this position relative toieaoh other by pivots 26 and spacers 27.... In addition, the end bars, as shown ingFig.,5 may have other spacers,

such as the pins 28 and block 29, upon which pins 28 brackets 30 are mounted which are I so screwed to the window sash 14 by screws 31. Each intermediate bar at pivot 26 has two links fitting within space 32 (Fig. 6) between the channels, each being directed toward the adjacent bar at which each terminates. Taking one pivot 26, for example, there are links 33 and 34, one going to each adjacent bar. Where thevarious links 33 and 34 cross there is a pivot 35 connecting them. The free ends of links 33 and 34 are mounted on a common pivot 36 which is mounted slidably within the two channels. Running blocks 37 and 38 are indicated also mounted on the pivot 36 for guiding the pivot in the channels.

Each side of the gate has the same structure and the links are sufficiently short so that in folded form of the gate the free ends on pivots 36 do not move beyond the center of the bar. Thus the gate may be folded and the links housed completely in the channel space, as shown in Fig.7 3.

In Fig. 4 a modification is shown in which a regular length of lower sash 40 is employed, the gate being secured by its lower bar 41 to the ledge 42 by screws 43. The upper bar 44 is securedvby bolts 45 to'a housing or casing 46 which is carried by the lower sash 40.

What I claim is: r i 1'. A window gate comprising a plurality of parallel hollow slotted bars, a pair of pivotally crossed links between the ends of each pair of adjacent bars, each link being pivoted at one end to one bar, and being mounted to an adjacent bar slidably lengthwise and internally of the bar.

' 2. A window gate comprising a plurality my signature.

of parallel hollow slotted bars, a pair of pivotally crossed links between adjacent bars,

each link being pivoted at one end to one bar v internally of the bar, and being mounted to an adjacent bar slidably lengthwise and internally of the bar. 7 I

3. In a window gate a pair of adjacent parallel bars each bar comprising two spaced channel members rigidly mounted together with'the channels face to face, links pivotally mounted at one end toone bar within the space between the channel members, and slidably mounted at the other end within the channel of the other bar, and guiding means pivoted to the link running in one of said channels.

4. A safety windowrcomprising in combination, a window frame, upper and lower slidable sashes, the lower sash being short to provide an opening between the window ledge and the lower sash in the'closed condition of the sashes,.and'an expansible window gate secured to the ledge and tothe lower sash, said gate in closed form filling and sealing the open space below said sash, and comprising parallel hollow slotted bars and link
